XpressRICH5

PCIe 5.0, 4.0, 3.1/3.0 Root Port, Endpoint, Dual-mode, Switch Port Controller IP Core with Native User Interface

XpressRICH5 is a configurable and scalable PCIe controller Soft IP designed for ASIC and FPGA implementation. The XpressRICH5 IP is compliant with the PCI Express 5.0 rev.0.7, 4.0, and 3.1/3.0 specifications, as well as with version 5.x of the PHY Interface for PCI Express (PIPE) specification. The IP can be configured to support endpoint, root port, switch port, and dual-mode topologies, allowing for a variety of use models. The provided Graphical User Interface (GUI) Wizard allows designers to tailor the IP to their exact requirements, by enabling, disabling, and adjusting a vast array of parameters, including data path size, PIPE interface width, low power support, SR-IOV, ECC, AER, etc. for optimal throughput, latency, size and power. PLDA is working hand in hand with multiple PHY IP vendors and Verification IP vendors to offer a range of integrated solutions for PCIe 5.0 at 32GT/s. PLDA XpressRICH5 PCIe IP is the #1 choice for ASIC, SoC and FPGA designers looking for an enterprise-class PCIe interface solution with a high-performance, low-latency, and flexible user interface allowing for a variety of use models. 

We are actively working with our PHY ecosystem partners to provide an integrated and validated PCIe 5.0 controller + 32G PHY solution on a variety of process nodes and for a variety of foundries, as well as on leading edge FPGAs from Intel PSG and Xilinx.

Our unmatched expertise in PHY integration means customers can confidently select the PHY IP that best fit their requirements.

PCI Express is a complex protocol, and customers may not always have the expertise, the resources, or the time required to meet their development schedule. Our Advanced Design Integration (ADI) team helps customers shorten their development cycle by proposing expert services in the following areas:

  • Integration of commercial and proprietary PCIe PHY IP
  • Development and validation of custom PCIe PCS layer
  • Customization of the PCIe IP to add customer-specific features
  • Generation of custom reference designs
  • Generation of custom verification environments

  • Internal data path size automatically scales up or down (256-, 512- bits) based on max. link speed and width for reduced gate count and optimal throughput
  • Dynamically adjustable application layer frequency down to 8Mhz for increased power savings
  • Optional MSI/MSI-X register remapping to memory for reduced gate count when SR-IOV is implemented
  • Configurable pipelining enables full speed operation on Intel and Xilinx FPGA, full support for production FPGA designs (when supported)
  • Ultra-low Transmit and Receive latency (excl. PHY)
  • Smart buffer management on receive side (Rx Stream) allows implementation of custom credit management schemes in the application logic
  • Merged Replay and Transmit buffer enables lower memory footprint
  • Optional Transaction Layer bypass allows for customer specific transaction layer and application layer
  • Optional QuickBoot mode allows for up to 4x faster link training, cutting system-level simulation time by 20%

The XpressRICH5 controller IP is integrated and thoroughly verified using multiple VIP for foolproof reliability. We use a combination of Avery VIP, Cadence VIP, Mentor VIP, PCIe testsuites, and a PLDA-developed verification environment to achieve optimal coverage.

Our rigorous verification process ensure customers can focus on the core of their application.
